How to manage connectivity between Oracle 11g &9i Database and Visual Studio 2010 professional in window 7

Hi,
I am not able to resolve the error of
“ORA-12514: TNS:listener does not currently know of service requested in connect descriptor”
Below Link is the indication, related to that error.

Hi Surbhi.Gupta,
Thank you for posting in MSND forum.
According to your descriptiom, I suggest you could try the following blog to connect to Oracle from Visual Studio check your issue again.
Reference:
http://blogs.msdn.com/b/kaevans/archive/2009/07/18/connecting-to-oracle-from-visual-studio.aspx
In addition, as you said the error message, I did some research about this error message. So I suggest you could refer then following thread to check your error, maybe you will get some useful message.
http://dba.stackexchange.com/questions/36370/oracle-11g-listener-fails-with-ora-12514-and-ora-12505-errors
However, since this issue is related to the third-party database oracle, so if possible, I suggest you could try to post your issue directly to this Oracle official website:http://www.oracle.com/us/corporate/contact/about-your-account-070507.html
, you will get better support.
Thanks for your understanding.

Difference between CR XI dev R2 and Visual studio 2010 CR

I have been working upon CR XI dev R2 which supports 64-bit application in 32 mode only. Now i want to switch to Visual Studio CR2010 to make our application a full fledged 64 bit application. So for upgrading from CR XI R2 to Visual Studio CR 2010 what features will i have to compromise. or i will put it this way " will CR2010 be worth enough (apart from being 64-bit) and does it supports all the features provided by CR XI dev R2"
Thanks

See the link at the top of this forum for more info on features and functionality

ODBC connectivity between Oracle 11G and MSSQL Server on Solaris 10

When we were running in 10G, I was able to successfully configure hsodbc using unixODBC and freeTDS to allow for an ODBC connection between Oracle and MSSQL Server.
A few weeks ago we upgraded to 11G and I've been struggling to get the connectivity (dg4odbc) working.
In our 10g environment unixODBC and freeTDS were compiled as 32-bit. I have recompiled them as 64-bit and switched over to an 11G listener and I am getting the following error:
ERROR at line 1:

Thank you for your response.
I modified the envs LD_LIBRARY_PATH parameter in my SID_LIST_LISTENERODBC to be:
(ENV="LD_LIBRARY_PATH=/usr/local/freetds/lib:/usr/local/unixODBC/lib:/u01/app/oracle/product/11.2.0/db_1/lib:/

and bounced the listener, but I'm still getting the same error.
I do not have a lib64 directory in my Freetds installation, but all the files in the lib directory are 64-bit.
Here is a listing of my DG4ODBC init file:
/u01/app/oracle/product/11.2.0/db_1/hs/admin[PPRD]> more initidentipass.ora
# This is a sample agent init file that contains the HS parameters that are

How can i connect between WS−G5484 1000BASE−SX and GLC-LH-SMD ?

Dear experts,
My customer has 6509 A-side and B-side core switches and need to migrate only 6509 B-side to Nexus.
I have some question below.
1. Customer's 6509A-side has multiple WS−G5484 1000BASE−SX and WS−G5486 1000BASE−LX links and it is connected to 6509B-side.
But customer bought only GLC-LH-SMD for Nexus migration of 6509B-side.
I understood BLC-LH-SMD doesn't support SX type, so I am worndering how i can connect between 2 different module ?
Or should i have GLC-SX-MMD for WS−G5484 1000BASE−SX links ?
2. Current Rack has LC type patch pannel from B-side to Rack A side.
But new Nexus A-side rack is located at different row and between these rack, there is only sc-type patch pannel.
So If i want to connect from LC-type to Sc-type patch pannel, how can i connect ? do i have to use SC-LC converter ?
3. Old 6509 links use many MMF cable, and new Nexus use SMF.
Between same LX/LH links, if a side use MMF and another side use SMF, how can i connect each other ?
Again new Nexus A-side rack is located at different row and between these rack, there is only sc-type patch pannel.
Please let me know in detail, Thanks in advance, I really appreciate for your help.
Jason.

Hi Leo,
Thanks of your reply.
Dear Experts,
I seek your expert's advice for another question urgently.
Please make you time and share your experiecce.

Slow connection to oracle 11g R2 database if no Internet connection

Hi all,
I've read some similar topics, but could not find a solution for my problem. I'm running Windows 7 Enterprise with a VMWare (Player) with a virtual Linux image on my machine (centos 5.4) in NAT connection mode. On the virtual machine I have installed an Oracle 11g R2 database. As long as I'm connected to Wi-FI or I'm plugged into my LAN network, I can access the database and run applications without a problem. But if I don't have an Internet connection, it's almost impossible to connect to the database or use certain applications.
Thanks in advance for your help !

How to set connection between oracle forms and DB?

I have installed win xp,
oracle database 10g in c drive ,
oracle forms and reports 10g in d drive ,
how do i set the connection between forms and DB ?
i know its an old question but i am very new to this !
thanks in advance.

You didn't mention the versions or whether you are using Developer Suite or Application Server. I guess it really doesn't matter in this case, but please provide complete information in the future.
In order to connect the F/R home to a db you will need to make the appropriate configuration entries in tnsnames.ora found in the F/R home (\NETWORK\ADMIN). The entry you add will be similar to the one found in the tnsnames.ora for the db which is found in a similar directory in the db home. The entry will look something like this:
ORCL =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = myMachine)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = myMachine)
)

Connection between oracle forms10g on XP and oracle db 11g on WINDOWS 7

Hello,
I am trying to connect forms 10g R2 to oracle 11g.
My forms is on windows XP inside VMware while my db is on windows 7 64 bit host.
i have tried all ways known to me and the ones i saw on the internet but none works.
I will be glad if you can refer me to a link that talks on this type of connection in details or any solution you can provide.
Thanks in anticipation
AbdurRahman

Thank you for your response,
1) I copied the tnsnames.ora,sqlnet.ora and listener.ora files from the database 11g on the windows 7 host to the DevSuiteHome_1\NETWORK\ADMIN path for the developer
suite 10g on XP Vmware.
2) I also entered the host address in the C:\WINDOWS\system32\drivers\etc\host file i.e 192.168.202.54 AAJANI-pc.
below are the details of my db and forms

Has anyone experienced check-in conflicts between RoboHelp 9 and Visual Studio 2010?

Here's a description of what happens when I try to edit the properties of more than one Single Source Layout (SSL) in a single RoboHelp session:
Open RoboHelp 9 project in Visual Studio 2010.
Edit the properties of a SSL named "Layout A". When prompted by RoboHelp, check out the .SSL file.
Save and generate the output.
Edit the properties of the SSL named "Layout B". When prompted to check the .SSL out from version control, click Yes. RoboHelp displays the Cannot Complete Operation dialog box: “The files in the list below could not be checked out from version control. Exclusive access to these files is required to execute the selected action.”
Shut down RoboHelp, re-open the project, and can then edit Layout B. I have to do this for each layout whose properties I edit.
As an experiment, check the .SSL for Layout C out of Source Control (“Check Out – Prevent other users from checking out and checking in”), edit the properties of the SSL, and click Check In All from RoboHelp. In Source Control, the file shows as checked in; in RoboHelp, the SSL shows as checked out (the red check arrow appears to the left). Checking everything in from within RoboHelp does not check in the SSL for Layout C, and when I try to edit the properties for Layout D, the Cannot Complete Operation dialog box appears.
Since I'm working with five SSLs, this problem is a nuisance (but not a showstopper). Should I be following a different process here?
Thanks for any assistance.
Chayah

It seems I was a bit liberal with moving the libraries linked to in the instant client, i.e. copying the lib file and the depending .dlls to another location.
Running the executable within the instant client directory with all dlls present solved this. I didn't realize this because DependencyWalker told
me everything was fine.

How to connect to oracle database from visual basic 2010 express edition

I have installed visual basic 2010 express edition on windows xp. But visual basic 2010 express edition supports Microsoft sql server database file,Microsoft sql server compact 3.5, Microsoft access database file. I want to connect to oracle database from visual basic 2010 express edition. So what drivers are required and how to do connectivity?

Hello,
I wasn't clear on what you were using to make the connection. I had a look in Visual Studio 2010 (don't have express to test sorry).
I think you mean the Data Sources available under the menu Data-> Datasources. this seems to match the description you give when I
look at the list of datasource options.
In here you can make ODBC connections via the Microsoft .net Data Provider .
If you select ODBC as a datasource you can see listed the DSN's you created - for example I see 2 which use the Oracle ODBC driver.
This assumes you installed an Oracle Client + the oracle version of the ODBC driver (comes with the oracle client).
Once you created a server connection then you should see it in the server explorer.
You can also download the Oracle Developer Tools for Visual Studio which is an add on for VS.
** I suspect this is only for VS 2010 and I didn't see that Express was supported.

Let me know if that helps.

Connecting to oracle 12c multitenant database

My question, using coldfusion 11 enterprise datasource gui,
how do you connect to oracle 12c multitenant database,
when you need to log into a pluggable database, beneath
the container database?
What's the connection string, or is it even possible to connect(?) because earlier versions of oracle
didn't use multitenant architecture, you just make a user/password,
grant connect privileges, and connect.
Using Oracle Linux 6.5 64bit.
This is assuming I can connect to the oracle CDB (container database) and PDB (pluggable database) from the shell using sqlplus.

Oracle 10g express, Windows Vista and Visual Studio 2005

Hello,
I have Oracel 10g express and Visual Studio 2005 professional, all installed on Windows Vista and working fine.
I want to use the .net tools but I have had problems to install the wright version for this environment. Has anybody have this same configuration working? What are the downloads I need to have and the steps to have the .net oracle tools working ?

It can be done:
1) Download and install XE. Don't download the special "ODT for XE"
2) Download and install ODAC 11g with ODT into a different directory than XE
3) Copy over the TNSNAMES.ORA from the XE install into the new Oracle home.

How to connect from Oracle 11g to SQL Server 2008 R2

Hi,
Is it possible to connect from Oracle 11g on AIX to SQL Server 2008 R2? If so, what is the preferred method?
SQL Server has the original table. From Oracle 11g, we want to access data which is in SQL Server real time.
Thank You

Hi,
Have a look at these Oracle notes for the full information on the gateways -
Master Note for Oracle Gateway Products (Doc ID 1083703.1)
Functional Differences Between DG4ODBC and Specific Database Gateways (Doc ID 252364.1)
Gateway and Generic Connectivity Licensing Considerations (Doc ID 232482.1)

How to Configure DG4ODBC on 64bit Unix OS (Linux, Solaris, AIX, HP-UX Itanium) to Connect to Non-Oracle Databases Post Install (Doc ID 561033.1)
The Database Gateway for SQL*Server (DG4MSQL) needs a separate license but the Database Gateway for ODBC (DG4ODBC) is included in your RDBMS license. You only need to provide the third party ODBC driver needed by DG4ODBC.
